Cost of Living Calculator

A cost of living calculator compares your monthly expenses in two locations and works out the salary you would need in the second place to keep the same lifestyle. Because you enter the costs yourself, it reflects your spending rather than a national index. With the defaults — $3,070 a month in Austin versus $3,580 in Denver, on a $90,000 salary — Denver costs $510 more per month, so you would need about $96,120 to break even.

The calculation

1. Sum five categories for each location: rent or mortgage, groceries, utilities and internet, transport, and other discretionary spending.
2. Monthly difference = total B − total A.
3. Cost index difference = (difference ÷ total A) × 100, shown as a percentage.
4. Equivalent salary = current salary + (monthly difference × 12).

Worked example with the defaults

Difference = $3,580 − $3,070 = $510. Cost index = $510 ÷ $3,070 = 16.6%. Equivalent salary = $90,000 + ($510 × 12) = $90,000 + $6,120 = $96,120. Rent alone accounts for $400 of the $510 gap, which is typical — housing usually dominates a relocation comparison.

Translating a monthly gap into a raise

Compare that annual figure with the gross offer. A salary that looks larger can still be a lifestyle cut once the monthly gap is annualized.

Common mistakes

• Using city averages instead of your budget. Average rent in a metro says little about your specific neighbourhood and apartment size.
• Leaving out taxes. Income tax, sales tax, and property tax vary by state and are not part of the monthly categories.
• Missing irregular costs. Insurance, car registration, and annual fees rarely appear in a monthly list but can differ sharply between locations.
• Forgetting the move itself. The one-time cost of moving, deposits, and setup is real and is not annual income.

Should I compare gross or take-home salary?

Take-home, if you can estimate it. The calculator scales gross salary by the monthly cost gap, but two cities with different income tax rates can leave the same gross salary with very different net pay.

Can I compare more than two cities?

Not in one pass. Use one city as the fixed baseline and re-run with each alternative; the equivalent salary it returns is directly comparable across runs.

Why does the tool ask for my salary at all?

The monthly totals tell you the size of the gap; the salary input turns that gap into a target number. Without it you know the difference but not the offer you should ask for.

How to use the result

1. Compare the equivalent salary with the actual offer. If the offer is below it, the move lowers your standard of living unless something else compensates.
2. Use the percentage gap as a negotiation anchor — a raise that at least matches it keeps you level.
3. Re-run with conservative and optimistic rent figures, since housing is the largest and least certain input.
4. Add the one-off costs the model excludes: moving, deposits, and replacing furniture that will not travel.

What if I do not know the costs in the second city?

Start with your current spending and adjust one category at a time, beginning with rent, which usually differs most. Keep groceries, utilities, and transport at their present values until you have evidence they change; guessing high in every category overstates the gap.

Does it account for a different lifestyle?

No. It holds your consumption pattern fixed and only prices it differently. Moving to a larger home, driving further, or eating out more often changes the pattern itself and sits outside the model. A useful sensitivity check is to double the rent gap, then halve it, and see whether the equivalent salary still changes your decision.

If the new role pays hourly rather than on salary, convert it first with the salary to hourly converter. To compare the after-tax price of goods in each place, the sales tax calculator handles the state and local rates.
